The connection of audio devices via USB, while it allows high-resolution and bit-perfect data to be passed through, was not created specifically for audio, however. It therefore carries both data and power, which means that there is potential electrical noise from, for example, the power supply of your computer. The iFi Audio iSilencer+ solves this problem by applying effective filtering by connecting directly between your computer and your DAC. It eliminates electrical noise and EMI/RFI interference for clear, accurate and faithful sound reproduction, while improving bass.

The iSilencer+ can also be used on an unused USB port of a computer or DAC to reduce EMI interference. Each additional unit doubles this noise suppression capability.

In this version, the iSilencer+ has a female USB-A input and a male USB-C output.

An improved version

The iSilencer+ is a direct enhancement of the iDefender 3.0, now taking advantage of the Active Noise Cancellation 2 technology as well as the REbalance technology to remove distortion.

The circuit has also been improved, now incorporating low ESR tantalum capacitors for better input and output filtering. The filtering capacity has thus been multiplied by 10.
